In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

Nanoparticles elicit neutralizing antibodies to diverse SARS-CoV-2 variants

Spike-protein-based nanoparticle vaccine candidates were retained longer in follicular dendritic cells and showed higher germinal center reactions in lymph node follicles compared to soluble spike protein vaccine.

New screening method detects cancer biomarkers more effectively

Early screening can mean the difference between life and death in a cancer and disease diagnosis. That's why University of Central Florida researchers are working to develop a new screening technique that's more than 300 times as effective at detecting a biomarker for diseases like cancer than current methods.

Could nanoparticle vaccines offer broad protection against sarbecoviruses?

To understand the ability of SARS-CoV-2 vaccine-elicited antibodies to neutralize and protect against emerging variants (that are pathogenic) and other sarbecoviruses, a large team of researchers studied immunity by receptor-binding domain nanoparticle vaccines. They showed that a clinical-stage multivalent SARS-CoV-2 receptor-binding domain nanoparticle vaccine (SARS-CoV-2 RBD-NP) protected mice from the SARS-CoV-2-induced disease.

Chimeric vaccines may provide universal protection against viruses like SARS-CoV-2

Researchers in the United States have developed “chimeric” vaccines that provided cross-protection against different strains of sarbecovirus in mice, including the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19).

Optimized SARS-CoV-2 vaccine candidate could be less reactogenic, say researchers

A new study, released as a preprint on the bioRxiv* server, reports an optimized coronavirus disease 2019 (COVID-19) vaccine candidate, which, claim the researchers, may be less likely to produce reactions like fevers. It may also have increased protective potential against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen that causes COVID-19.

Self-assembling nanoparticles an effective vaccine candidate for SARS-CoV-2

The currently developed vaccines against SARS-CoV-2 include the RBD in their immunogen. With a similar objective, a new study developed an RBD protein-based vaccine candidate against the SARS-CoV-2, using self-assembling Helicobacter pylori-bullfrog ferritin nanoparticles as an antigen delivery system. The study is published recently in the journal mBio (by the American Society of Microbiology).

Data from Israel’s vaccination program suggests Pizer-BioNTech COVID-19 vaccine induces strong host antibody response

A team of scientists from Israel has recently evaluated the efficacy of an mRNA-based coronavirus disease 2019 (COVID-19) vaccine, BNT162b2, in inducing host humoral immune response. The findings reveal that the vaccine is capable of inducing strong anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody response and that the response varies significantly with age. The study is currently available on the medRxiv* preprint server.
